PAPER-BAG-MAKING APPLIANCE.

SPECIFICATION forming part of Letters Patent No. 700,467, dated May 20,1902.

- Application 516a January 13, 1902. Serial No. 89,429. (No model.)

To all whom it may concern: Be it known that I, DANIEL APPEL, a citizenof the United States, residing at Clevej land, Ouyahoga county, Ohio,(post-office address No. 62 Holyoke Place, Gleveland,0hio,) haveinvented certain new and useful IInprovements in- Paper 5 Bag MakingAppliances, (Case 0,) of which the following is a specification.

This invention pertains to an appliance for ance exemplifying myinvention; Figs. 2 and 3, the latter to be viewed as a continuation atthe right-hand end of -the former," a per-, spective view of a plicatedpaper tube in various stages of progress in being formed into a paperbag by the aid of my appliance; Fig. 4, a perspective View of thecomplete bag in condition for the market; Fig. 5, a perspective view ofthe bag opened out for use, and Fig. 6 a perspective View designed toserve in demonstrating more clearly and oh a larger,

scale some of the main steps of progress in using my appliance.

My appliance is designed to dealwith a, p'licated paper tube withordinary bellows folds at its sides." In the drawings, 1 indicates sucha plicated tube while in flattened condition; 2, oppositely-disposedtransverse cuts through all of the plies of the tube, but

- extending inwardly a distance less than that duced and then the tubeopened up to its full depth, the tube having a tapering enlargement tothis station-point from the earlier point,where it isinfiat condition;5, another station-point in the tubea section length still farther inadvance, the tube still being in expanded condition, but vertical cut 6at the sides in extensionof the cuts 2, previously referred to, havingcompleted the severance at the sides of the tube and a stripe of paste 7having been applied just rearward of the transverse cuts and extendingtransversely across the two sides and .the upper face-ply of the tube;8, another station-point in the tube a section length still farther inadvance, at which point the forwardly-presenting end portions of thesides of the tube have been folded squarely inward, as at 9, to form theunder plies of the future bottom of the bag, the two face-plies stilluniting the bottom of the section to the mouth of the section ahead; 10,another station-point on the tube a section length still farther inadvance, at which point the bottom end-of the section previouslygotten'into the condition indicated the tapering contractionof the tubehas.

broughtit to almost a collapsed condition, but not sufficiently so tobring into contact the pasted surfaces of the infolded bottom portions,the general; portions. of the tube thereafter remaining in collapsedcondition;

13, a still farther advanced station-point,

where'the section in advance of the station has been retracted somewhat,thus causing the bottom members to begin to flex upwardly anddownwardly, these partsapproachinga plane at right angles to the generalplane of the collapsed tube; '14, a station'stillfarther in advance, atwhich point the section'ahead of the station has been completely severedfrom the section to the rear of it and the preyiouslyinfolded bottommembers brought into a common plane and the severed fiaps foldedandpasted against them to form' the complete double bottom'ofthebag;'15,the com pleted bag which has been severed from the tube andhas had its completed bottom folded fiat down upon the tube and pressed,and 16 the completed bag when opened out ready for use.

My improved appliance is designed to facilitate the carrying out of theabove-described program and will be found efficient in connection witheither hand or machine operations upon the tube.

Attention is now called to Fig. 6, which is a demonstrative figuredesigned to bring out certain conditions which cannot be clearlyexhibited while the tube-sections remain unsevered. It is to be observedthat before the bottom members 9 are folded inward the inside of thetube is unobstructed for its full width, but that after these membersare folded inward they largely obstruct the tube, leaving clear,however,a vertical slot bounded on its sides by the inner extremities ofthe bottom members 9 and on its ends by the upper and lower face-pliesof the tube. If the infolded bottom members 9 are so proportioned as tomeet or lap, then even this slot will not be present; but it will beobserved that there will be a thin passage-way over the lower face-plyof the tube below the horizontal portions of the inturned bottommembers, this passage having a width equal to the distance between thelongitudinal cuts 3, heretofore referred to, there being a similarpassage just below the upper face-ply of the tube. To put it in otherwords,while the tube is in the conditions indicated at station 5 inFig.- 2 its interior is entirely unobstructed, and after it has reachedthe condition indicated at station 8 then disregarding the verticalslot,which may or may not be present, there would only be space for thepassage past the station of a thin blade at the floor of the tube andanother at the ceiling of the tube, the blades having a width notgreater than the distance between the longitudinal cuts in thefaceplies. Now turning to the appliance illustrated in Fig. 1, whichtakes on the form of a big mandrel over which the tube passes, 17indicates a pair of thin blades lying one above the other and having awidth equal to that of the plicated tube to be dealt with, these bladesbeing separated from each other such distance as will readily permit thepassage of the inner bellows folds of the tube, the form of this portionof the mandrel being such as to accommodate the tube in its collapsedcondition; 18, transverse slots or notches in this portion of themandrel, of use in facilitating the cutting of the transverse slits 2through all of the plies of the tube; 19, a forward-tapering divergingprolongation of the two blades; 20, the forward extremity of thisprolongation, at which point the distance between the two blades isequal to the height of the completely-opened tube, the transversedimensions at this point therefore representing the transversedimensions of the fully-opcned tube; 21, forward-tapering convergingprolongations of the tube-blades, this portion of the blades having awidth about or not greater than that between the longitudinal cuts 3 ofthe tube; 22, the forward extremity of the narrow portion of themandrel, the blades at this point being such distance from each other asto accommodate at least two thicknesses of the paper of the tube,and 23a portion of the narrow blade parts just forward of extremity 20 of thewide part of the blades, this portion of the narrow part of the bladesnot partaking of the tapering convergence characterizing the balance ofthe narrow part of the blades, but, on the other hand, maintaining thefull distance apart corresponding with the height of the opened tube. Ita collapsed tube be fed from the leftover the mandrel, it may have thetransverse cuts 2 readily produced at the notches 18 of the mandrel, andthe longitudinal cuts 3, extending through only the face-plies can beproduced without any special provision. If the tube be then pulledforward on the mandrel, it will be expanded, as at station-point 4 inFig. 2, and the completing side cuts thus may be produced at the sidesand the paste 7 may be applied, producing the condition indicated atstationpoint 5. It now the tube be drawn forward upon the mandrel tillthe proper point for the infolding of the sides comes to the forwardextremity 20 of the wide blades, then the ends of the tube sides may befolded inward to produce the condition indicated at stationpoint 8 inFig. 2. The unconverging portion 23 of the narrow blades keeps the faceplies fully separated and permits the bottom members 9 to be properlyfolded inwardly. This operation brings portions of the infolded bottommembers between the narrow blades, so that those blades occupy positionsin the thin passages heretofore referred to as existing between theface-plies and the contiguous infolded bottom members. If the tube benow pulled farther along the mandrel, it and its bottom folds willbecome collapsed, first as indicated at station-point 10 and then as indicated at station-point 12. By retracting the foremost section relativeto the section following the bottom members may be expanded, asindicated at station-point 13, and when the tube-point in this conditionreach es the extremity 22 of the mandrel then the bagsection in advancemay be severed and the bottom formation may be completed, as indicatedat station-point 14:, and then the bottom maybe folded flat and pressedas it leaves the mandrel, as indicated on the completed bag at 15, thebag thus completed being severed from the section following when the bottom work of the latter section reaches the extremity of the mandrel.

It is manifest that the operations described may be performed, inconjunction with the mandrel, manually when by the aid of simplemechanism disposed at various points along and cooperating with themandrel. The mandrel well lends itselfto employmentin connection with anordinary tuber to receive the plicated tube directly from the tuber, theinitial portion of the mandrel forming, if desired, the usual former ofthe tuber and finding its support by exterior devices connecting with itthrough the still open seam of the tube.

I claim as my invention- 1. In a paper-bag-making appliance, a mandrelcomprisinga pair of thin blades disposed contiguous to each otherat oneportion andthence having a tapering divergence, the

width of the blades being equal to that of the plicated tube to be dealtwith, and the greatest distance between the blades being incorrespondence with the fully-open condition of the tube, said bladeshaving narrowed prolongations from their point of greatest divergence,and said narrowedprolongations having a tapering convergence,substantially as set forth.

2. In a paper-bag-making appliance, a man drel comprising a pair of thinblades'disposed contiguous to each other at one portion and thencehaving a tapering divergence, the width ,of the blades beingequal tothat of the plicated tube to be dealt with, and the greatest distancebetween the'blades beingin correspondence with the fully-open conditionof the tube, saidblades having narrowed'prolongations from-their pointof greatest divergence, and said narrowed prolongations having atapering convergence, the convergence of said narrowed prolongationsbeginning at a point some distance forward of the juncture between thewide andnarrow portions of the blades, substantially asset forth.
